and CHARLES A; HINEMEYER, citizens of the United States, residing atToledo, in the ,county of Lucas and State of Ohio, haye invented new anduseful Improvements in is a specification.

The present invention provides means for automatically giving warningwhen a vehicle has attained a predetermined speed when in operation sothat due caution may be exercised to prevent excessive speed.

The invention contemplates a" speed indicating appliance adapted mostespecially for automobiles and like mechanically propelled vehicles tobe attached to a wheel thereof for giving an audible signal when thevehicle in motion attains a predetermined speed. i

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the accompanying drawing, andpoint'ed out inthe appended claim.

Referring to the drawing, forming a part of the specification,

Corresponding and like parts are re ferred to in the followingdescription, and indicated in all the views of the drawing,

, by the same reference characters.

The mechanism embodies afcasing 1 which I is adapted to be secured toawheel of the vehicle in any manner and as shown said casing is providedwith aiclamp 2 to be fitted to a spoke of the wheel. The casing 1 has alongitudinal slot 3 in a side thereof near one end and its opposite endis open and internally threaded for a short dis.- tance. A weight 4 isloosely mounted within an end portion of the casing 1, designatedhereinafter as the inner end, in counterdistinction to the endwhich-faces outward and is provided with the inner s'crewthreads. Atappet 5 has connection with the weight 4 to move therewith and consistsof a machine screw, the head constituting the tappet and the body of thescrew passlng through,

the slot 3 and entering a threaded opening a formed in a side of theweight a. The length of the slot 3 practically determines the movementofthe weight 4. A helical spring 6 is'located in the outer portion of thecasing 1 and exerts an inward pressure upon the weight a. The effectivetension Specification of fitetters Patent.

gong bell 9 may be connected with any con- I venient part of the vehicleand as shown an arm 10 supports the bell and in turn is connected to a'part of the axle 11. The bell 9v is adjusted with reference to thetappet 5 Q so that when the vehicle is moving at a."

speed less than the predetermined speed the tappet 5 will remain spacedfrom the bell so as not to sound an alarm, but whenthe 1 speed of thevehicle attains the predetermined degree the tappet 5 is caused to comein contact with the bell 9 and sound an alarm.

When arranging'the parts the casing 1,

which is oblong, is placed in line with a radius of the wheel and issecured by means" a of the clamp 2 to a spoke thereof, the endcontaining the weight 4 facing inward so spring 6 and when the speed ofthe vehicle.

is reduced so as to fall below thepredeterthat when the vehicle is inmotion the weighti 4 tends to move downward by centrifugal mined pointthe spring 6 reacting moves the weight 4 inward and carries the tappet 5away from the bell. It will thus be understood that the inventionprovides simple and effective means for apprising the driver or operatorof a vehicle when the speed reaches a given point so thatproper care maybe exercised to guard againstflexceeding the limit. I

' From the foregoing description, taken in connection with theaccompanying drawing the advantages of the construction and o. themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while we have described theprinciple of operation of the invention, together with the device whichwe now consider to be the embodiment thereof, we. desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when de-- sired as are within the scope of the claimap ended hereto.

aving thus described is claimed as new, is n a speed indicator, thecombination of a signal device, side and having threaded, a weight loosewithin the casing,

In testimony whereof we afiix our signatures inpresence 'of'two witnesses.-
